At the peak of his '80s excess, Italian sleaze maestro Bruno Mattei using the alias Stefan Oblowsky stunned audiences with this Nunsploitation shocker about a series of brutal murders in a depraved convent. And while his cinematic legacy may remain controversial, Mattei delivers a surprisingly stylized yet undeniably blasphemous orgy of stabbings, stigmata, Satanism, violence and graphic savagery that ranks among his very best. Franca Stoppi (THE TRUE STORY OF THE NUN OF MONZA), Carlo De Mejo (WOMEN'S PRISON MASSACRE) and Franco Garofalo (HELL OF THE LIVING DEAD) star in this nugget written by the notorious Claudio Fragasso (RATS: NIGHT OF TERROR, TROLL 2) and featuring a score borrowed from Goblin, newly transferred from a 35mm print discovered behind a false wall in a Bologna nunnery!
